Fats, Oils, & Grease Program

Fog is any combination of animal fats, and/or vegetable oils that are used to prepare food, or are found in food. When discharged into sewer lines, FOG accumulates and sticks to pipe walls, causing clogs in the sanitary sewer system. The most significant sources of FOG are residential homes and Food Service Establishments (FSEs) where cooking oil and residual grease from dishes are improperly disposed of in drains.
